Moist Pak-D insulation is used primarily as a surface layer over Fiberfrax blanket linings in hot gas erosion applications. It is also used to protect alloy hardware exposed to high temperatures, as a durable insulating cover for exhaust lines, around burner assemblies, and wherever a formable blanket is needed to provide strength and hot gas erosion resistance.

Moist Pak-D is ideal for insulation of complex shapes and for service under conditions of high hot gas velocities. The material is packaged in a clear polyethylene bag to retain the wet binder during shipment and storage.
